2 SHEETS-SHLET 2- INVENTORS. FH'D If. MUJ HY. ALBERT W- MARI/IV Lou/.1- cwmvnoumv Y ATTORNEYS restore the collar 5 to substantially its normal thickness and width when the disk is attached to the end of the journal.

In applying the disk to the end of the journal the plug 11 is entered in the recess 12 andthe end of the axle again subjected to heat and brought to a welding temperature, after which it is again placed in the die chamber 7. The disk 10 is then welded to the end of the journal 3 by delivering blows thereagainst with a plunger 13. The axle is then removed from the die and machined down until it is brought to the proper dimension, thereby producing as perfect an axle as when the axle was originally made, and this operation may be repeated.

his manner of treating the axles to restore them to their original condition may be accomplished at a minimum of expense, and at the same time a great saving in material is made as it has been customary in the past to junk such axles as they became Worn, without attempting to restore them to their usefulness.

The invention claimed is:

l. The process of reclaiming worn car axles consisting in extending the journal portion of a car axle to its original bearing dimensions from the original journal stock and adding metal to the non-bearing part of the journal to restore the journal portion of the axle to its initial dimensions.

2. A. process for reclaiming worn car axles, embodying the heating of the journal ends of the car axles to a forging heat, expanding the heated portion of the axle, applying additional metal to the end of the journal, subjecting the end of the axle and the added metal to a welding heat and then welding the added metal to the end of the journal, the expanding ot' the journal and the addition of the metal restoring the our nal portions of the axle to their initial di mensions.

3. The process of reclaiming worn car axles, which process consists in heating the journal ends to a forging heat, expanding the same while heated by forming a recess in the ends thereof, filling said recesses with metal, and welding the added metal thereto for restoring the parts of the journal to their initial dimensions.

In Witness whereof, we have hereunto aflixed our signatures.
